ABSTRACT’s File Analysis option shows information about a selected file through a tabbed interface.

The External Layout tab shows the external definition of the record format. If the file has more then one format, you may click on the name of the format for which you want to see information. Each field in the format will be shown in positional order along with its attributes, length and text, if any. You may right-click on a field name to show options available for that field.

When available, the Internal Layout tab provides information about your application’s use and definition of program described files. If programs in your application use record or field definitions that are different from the external definitions in the database, ABSTRACT will acquire and store the program descriptions in its database. The program which provides the description is shown in the display, and its use of the field is also indicated.

The Database Relations tab depicts database structure and access path information. Use it to determine the relationships among the physical and logical database files in your application. This example lists the database structure in which the CUSTMAST file participates. Each member of the physical files in the structure is represented at the leftmost position of the file name column. Logical file members that are built on the physical file member are listed underneath it and indented to the right. Access path information is listed to the right of the file and member name.

The Members tab shows information for each database file member (this option is not available for device files). For each member, a count of active and deleted records is shows, as well as member text.
